Ok, long term review, one of my vehicles is a 2007 Tahoe (5.3L), I started using the Signature Series about 100,000 miles ago after the vehicle already had 150,000 miles on it. Upon the first change I noticed a difference in oil pressure, the dreaded GM cylinder shut off system and lasting longer between changes. It's still running well after 260,000 miles and I have hope for many more miles. I only wish I had started sooner with this product.

Great oil, easy fast shipping.

What's there to say it's just good oil!!!

It’s a great kit. The 1 gallon containers are great compared to the competitors 5quart. Everything you need with one click. I just started using AMSOIL in my truck this year after using Mobile1 for years. It’s a bit pricey but it’s piece of mind knowing your using the industry best in your engines. I’ve also started using it in Briggs&Stratton home standby generators as the air cooled models can run very hot.

This oil is the best! Vehicle runs great and oil packaging is perfect.

I switched to amsoil after I spun a rod bearing. Right off the bat I noticed lowed oil temps when driving around using the same weight as the past stuff. The car idles smoother than before.

Been using amsoil for many years. Far superior to anything else on the market. Signature motor oils will help your engine run cooler and last longer.

Works great and they were awesome to include gloves and funnel as well as a sticker for the next oil change. I use amsoil for everything 👌

Amsoil is the best I have used! This is a proven oil when you need a bit more viscosity for larger clearances.

Not my first rodeo with Amsoil. Ran it 30 yrs ago in my motorcycle... Decided to run it in my new Bronco Raptor. Won't run anything else in it.

I started using AMSOIL in my 1984 Z28, continued through all following vehicles we have owned. A '91 Silverado, '99 Z28, '04 Corvette, '04 Tahoe and our new '23 ZR2 Colorado. We have retained the Tahoe (seriously modified) and the Colorado. We sold the others. The common thing that has kept us using AMSOIL is that when I check the oil level, it is always full and still clean. We have had no weeps or leaks on any of the motors. Can't beat that! And I did and still do all the maintenance on all of them.

Does it's job, definitely improves performance and my car loves it

My mechanic had used this oil on my 2017 GMC Terrain a few years back and I’ve never had any issues with this product. It’s the only oil I’ll ever use and my new mechanic is a fan of this oil. Will be re-purchasing often from now on.

Great product and fast shipping will buy again

We bought my wife's Altima new in November 2013. Fall of 2014 I was doing my second oil change and switched to this product and have used it ever since. I change the oil/filter every fall and in the spring I change the filter and add some fresh oil. The car has 145k on it and still doesn't use any oil. It has changed me and I am now all Amsoil in everything I run.

Would definitely recommend and purchase again!

Would definitely recommend and purchase again!

This oil is worth the extra money, to protect the ridiculous amount of cash,We pay for our vehicles. Amsoil has never failed me.

great products, worth the extra $ for the piece of mind.

I ordered oil and a filter to change the oil in the LS3 in my C-10. It was shipped quickly and the gloves, filter and oil change sticker were a nice surprise.
